What Is Computer Vision?
Computer vision is a field of AI that enables computers to interpret and understand visual information from images and videos — just as humans use their eyes and brain to see and recognise objects.

Questions & Answers
What is computer vision?
Computer vision is a field of AI that enables computers to interpret and understand visual information from images and videos — just as humans use their eyes and brain to see and recognise objects.
How does a computer 'see' an image?
A computer stores an image as a grid of tiny squares called pixels. Each pixel has a numerical value representing its colour and brightness. AI models analyse these numbers to find patterns that identify objects, faces, or scenes.
What is image classification?
Image classification is the task of looking at an image and assigning it to a category — for example, deciding whether a photo shows a cat, a dog, or a car. It is one of the most common tasks in computer vision.
Where is computer vision used in real life?
Computer vision is used in: medical imaging (detecting tumours in X-rays), self-driving cars (identifying pedestrians and road signs), face unlock on phones, quality control in factories, and augmented reality apps.
